What term refers to any two or more alternative forms of a gene?

• A. Allele
• B. Genotype
• C. Phenotype
• D. Food web

Answer: (A)

Alleles are the alternative forms of a gene. Each gene sits at a specific place on a chromosome, and different versions can exist at that spot. In individuals with two chromosome copies, there are usually two alleles for a gene, which can be the same or different. The combination of these alleles determines genetic identity for that trait (the genotype) and, together with how the organism expresses that genetics in its environment, the observable trait (the phenotype). A food web is an ecological concept and not related to genes.
